'The Bachelorette' Why does Drew Kenney leave the show?

We saw sparks fly between Drew and Desiree during his hometown date and he even told Des that he loved her. So what went wrong? In the upcoming preview of The Bachelorette, we see Desiree clearly upset and Drew possibly leaving the show.

Why does Drew Kenney leave The Bachelorette and leave Desiree, the girl he's clearly in love with? Here's what we know! Bachelor spoiler alert!
According to Bachelor blogger, Reality Steve, Drew gets sent home (or eliminates himself) the week after The Men Tell All. This means that Desiree's final two men are Chris and Brooks. We don't know exactly what happened between Desiree and Drew but rumors are Drew might be our next Bachelor.

Harrison tells TV Guide, "Drew's life might be very attractive to some. He's a very serious man,
settled into who he is and what he wants. He's just not the crazy,
happy-go-lucky guy who's going to bring the snow cone truck to school." Do you want to see Drew Kenney as our next Bachelor?
